Matsunoya Nansan-dori is a chain restaurant on Nansan-dori in Osaka that serves tonkatsu, katsudon, and katsu curry. For the tonkatsu, you choose the rice portion and either a single or 1.5 serving, and miso soup comes with it. It is open 24 hours, and orders are placed at a kiosk that supports Korean; you check the number on the screen and pick up the food. The interior is not large, so it is cramped when bringing a suitcase.
